CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation of co-pending U.S. patent applicationSer. No. 12/314,194, filed Dec. 5, 2008, titled “A Method Of ProvidingProximity-Based Quality For Multimedia Content,” which is commonly ownedwith this application and is hereby incorporated by reference in itsentirety.

TECHNICAL FIELD

The present invention generally relates to a method of and a system forlocation-based digital rights management and, in particular, to a methodof and a system for varying the quality level of a broadcast ormulticast of media content to a user based on proximity to a location.

BACKGROUND

In general, commercial enterprises often try to entice potentialcustomers to come to their place of business by offering unique servicestied to their physical, geographic location. For example, many cafesoffer free Wi-Fi access to their customers. Consistent with the presentinvention, a system is contemplated in which digital inducements areattenuated or degraded, based on proximity of a user to a particularlocation.

SUMMARY

The present invention relates to a method of and a system for providinga proximity-based quality for multimedia content, wherein the qualitylevel of the presentation of the multimedia content is intentionallycontrolled to act as a proximity-graduated inducement for nearbyusers/customers to come physically closer to a particular location sucha commercial place of business.

According to one aspect of the present invention, either full access tothe encrypted digital signal or degrading access to, for example, amedia library is contemplated.

For example, to gain full access to the encrypted digital signal, usersmust actually enter the location of the place of business. Morespecifically, the signal is encrypted in such a way as to be morevaluable to the user the closer the user is to the place of business.Accordingly, the further from the physical location of the place ofbusiness the user is, the more the signal is intentionally attenuated ordegraded, in a variety of useful ways. Moreover, the forms of theparticular signal attenuation are configurable by the publisher of thedigital signal.

Thus, the present invention provides a method of providingproximity-based quality for multimedia content, comprising: transmittingmultimedia content; and intentionally controlling a quality level of apresentation of the multimedia content based on proximity of a user to aparticular location.

The present invention further provides a system for providingproximity-based quality for multimedia content, comprising: means fortransmitting multimedia content; and means for intentionally controllinga quality level of a presentation of the multimedia content based onproximity of a user to a particular location.

The present invention still further provides a computer readable mediumcomprising software for instructing a system to: transmit multimediacontent; and intentionally control a quality level of a presentation ofthe multimedia content based on proximity of a user to a particularlocation.

DETAILED DESCRIPTION

The embodiments set forth below represent the necessary information toenable those skilled in the art to practice the invention and illustratethe best mode of practicing the invention. Upon reading the followingdescription in light of the accompanying drawing figures, those skilledin the art will understand the concepts of the invention and willrecognize applications of these concepts not particularly addressedherein. It should be understood that these concepts and applicationsfall within the scope of the disclosure and the accompanying claims.

FIG. 1 illustrates a system 10 for providing proximity encrypted signalsaccording to an exemplary embodiment of the present invention. Inparticular, the system 10 includes a transmitter means 20 fortransmitting multimedia content, for example, in the form of a digitalsignal from a sample location. The digital signal may be sent, forexample, over a network such as a wireless network, but is not limitedthereto. Alternatively, and as discussed in more detail below, an 1Pv6type network environment could be utilized wherein the signal to usersin a particular zone is a content stream wherein the content could bemade available via a multicast stream, allowing multiple users access tothe content without wasting limited wireless bandwidth.

The transmitter means 20 communicates with a content server 30 whichincludes, for example, a media library such as a music library 35. Auser 15 may gain access to the content server 30 to obtain the signalusing a mobile device 50. Access of the user's mobile device 50 to thecontent server 30 may be based on, for example, a license granted by alicense server 40. The content server 30 and the license server 40 eachmay be implemented in software, hardware, or a combination thereof. Thecontent server 30 comprises means for intentionally controlling thequality level of the presentation of the multimedia content based onproximity of a user 15 to a particular location.

By way of example, the sequence of events would be as follows: (1) alicense is created and stored in the license server 40; (2) the user 15having the mobile device 50 desires to acquire content from the contentserver 30, such as music from the music library 35; (3) the samplelocation such as a cafe transmits a digital signal from the transmittermeans 20 in the form of music from the music library 35; (4) uponattempting to gain access, the license server 40 validates the user's 15license to obtain the digital signal from the transmitter means 20 whichoriginates the digital signal from the cafe; and (5) the user 15 is thenable to play the content in the form of music over his mobile device 50.The amount of attenuation of that signal based on the user's 15proximity to the origin of the digital signal (e.g., the cafe) and otherfactors will be discussed in more detail below.

The system 10, including the transmitter means 20, the content server30, and the license server 40, allows the publisher or transmitter of a,for example, digital signal, a type of fine-grained control over theattenuation of the digital signal over proximity zones surrounding thesignal origin. As indicated above, the signal origin may be a place ofbusiness, such as but not limited to a cafe. The proximity zonessurrounding the signal origin will be discussed in more detail belowwith respect to FIG. 4.

Moreover, although the above embodiment describes the transmitter means20 as being identified with or located at the place of origin such as acafe, the present invention is not limited to such a configuration. Inother words, the proximity zone where a user 15 has access to the full,unattenuated signal, such as a cafe, does not itself have to transmit asignal at all. For example, a signal “manager” can operate to tie all ofthe proximity zones to a particular location (e.g., a cafe) but not havethe means to transmit the signal(s) from that particular locationitself. Moreover, the signal does not have to be provided by a wirelessmechanism from the designated “full axis area”, such as a Wi-Fi node,but can be provided by a wireless mechanism, such as a Wi-Max orlong-term-evolution (LTE) which is not located at the location of originsuch as the cafe. In this exemplary embodiment, a site can manage aproximity-attenuated signal without actually transmitting anything fromthe location itself.

Another example of a scenario where the center of the proximity zonesand the signal origin are totally separate would be as follows: a coffeecompany such as CoffeeShop has multiple coffee shops or stores and setsup CoffeeShop.com as the signal source, with each of the individualcoffee shops having proximity zones. The signal source (i.e.,CoffeeShop.com) is provided location information such that the signalsource can provide a mobile device 50 access to CoffeeShop.comcontent/stream based on proximity zone information of a specificCoffeeShop store.

FIG. 2 illustrates, from the user's 15 perspective, the process ofutilizing the mobile device 50, which may be a smart phone such as, forexample, an iPhone®, to request content from the content server 30. Forexample, assuming that the user 15 has been granted access, the user 15first makes (1) a content request to a request processor 36 of thecontent server 30. Then, (2) the content server 30 determines anappropriate proximity zone based on information in a proximity zonedatabase 37. The content server 30 then (3) provides a content responseto the mobile device 50.

The diagram illustrated in FIG. 2 is merely illustrative and thoseskilled in the art will recognize that there are many different possiblevariations in the basic flow that vary the type of contentrequest/response, location identification method, and/or proximity zonedetermination.

The content request types include content stream, content playlist,content item, etc. For example, a content stream request may result inthe content server 30 responding with a unicast stream directly to theuser 15. Alternatively, the response may include a reference (URL) andcredentials (key, password, etc.) that allow the mobile device 50 toretrieve the content stream from another server.

As another example, a response to a content playlist request identifiesa list of songs with references/credentials to retrieve those songs fromvarious servers. Alternatively, the content server 30 may be aware ofthe content residing on the mobile device 50 and the playlist comprisesthat content. The content response may include additional information toassist the mobile device 50 and its user 15. For example, the mobiledevice 50 is provided with a list of all the proximity zone locations sothat the mobile device 50 can show a user 15 something like the image ormap that is shown in FIG. 4.

The proximity zone locations can be used by the mobile device 50 todetermine when it needs to switch proximity zones. For example, inproximity zone A the user is listening to a low-quality country streamand as the mobile device 50 approaches proximity zone B it obtains andmerges in the higher quality version of that stream.

The location identification methods include but are not limited toglobal positioning system (GPS) coordinates, wireless triangulation andso forth. The mobile device 50 may provide the location information tothe content server 30, provide a location identifier that can be used tocontact a third-party to retrieve location information, and/or thecontent server 30 triangulates the mobile device's 50 location.

The proximity zone determination is based on the location information,however, there may be one or more applicable proximity zones. A locationmay have one or more proximity zones or a proximity zone may have one ormore configurations. The present invention contemplates using a numberof different possible factors as discussed in more detail below, but oneexample is that three different proximity zones are applicable at aspecific location: proximity zone A is a country music stream, proximityzone B is rock music stream, and proximity zone C is a jazz musicstream. The selection may be based on a user 15 profile (e.g., the user15 likes jazz), or subscriber level (unlimited music streaming), orcurrent load (e.g., select the country multicast stream because anadditional client will not adversely affect the server whereas the othertwo zones are unicast and would require more server resources).

As an alternative, the mobile device 50 may be provided the list ofproximity zones and the user 15 can select which one. As yet anotheralternative, the content server 30 may personalize the proximity zonefor each user 15. For example, the system 10 creates a low-qualitystream for users 15 in the proximity zone and constructs the contents ofthe stream based on their content profile/preferences (e.g., user A getsa low quality country stream, user B gets a low quality rock stream).

As a still further alternative, the content received by all of themobile devices 50 regardless of the proximity zone is the same. However,the mobile devices 50 are provided with instructions, based on theproximity zone in which they are located, that adjusts the content. Forexample, a mobile device A and a mobile device B both receive the samecontent stream. However, mobile device A is in a proximity zone 1 whichis a high-quality zone and therefore the system 10 does not modify thecontent. On the other hand, a mobile device B is in a proximity zone 2which is a low-quality zone such that the system 10 downgrades thecontent. The instructions could simply be a different set of rightsexpression language (REL) which the digital rights management (DRM)component on the mobile device 15 enforces.

FIG. 3 illustrates the management of a plurality of proximity zones fromthe perspective of the content server 30.

The proximity zones can be statically defined for geographical areasand/or dynamically constructed based on a number of factors outlined inmore detail below. FIG. 3 illustrates the content server 30 dynamicallydetermining the proximity zones. First, the content server may discoveror (1) identify the mobile devices 50 passively via their requests(e.g., they ask for content), or pro-actively by querying devices orasking a third-party location service 60 for a list of nearby devices.Second, the content server 30 then utilizes a proximity zone manager 38to apply rules that (2) determine how to construct proximity zones basedon the mobile devices 50 in proximity or predicted to be in proximity.Third, the content server 30 (3) stores the proximity zone informationin the proximity zone database 37 for use when it services user 15requests.

As far as the creation of proximity zones, for example, the geographiclocations for proximity zones may be static—however, the mediaaccessible in a proximity zone can be dynamically determined by thesystem based on the aggregate of the profiles of user mobile devices 50in or around the zone. The system may be configured to construct anynumber of streams or access rules—e.g. based on the aggregate, thesystem can create “rock”, “country”, and “easy listening” streams inmedium quality. Further details regarding the creation of proximityzones are set forth below.

The process shown in FIG. 3 may execute on a fixed schedule (e.g., everyhour), based on a number of mobile devices 50 in a given area, or betriggered manually by an operator. Just as an alternative solution,there may be “generations” of proximity zones. That is, at 8:00 am, theprocess fills in the particular content that is usable in proximityzones—the information is applicable to the devices that were used toconstruct that particular content availability—at 8:15 am, the processexecutes again and it excludes the previously identified mobile devices50 from the calculations.

The system 10 further allows the place of business to exercise controlover the attenuation of the signal by reliably determining the locationof potential users 15 and, for example, providing appropriate encryptionkeys to the users for controlling the quality level of the presentationof the multimedia content for a particular proximity zone.

The system 10 further allows the place of business to control theattenuation or degradation, over distance and direction, of qualitiessuch as but not limited to the following:

-   (1) Sampling rate,-   (2) Access to newly released music,-   (3) Duration of the provided musical tracks,-   (4) Size of the media catalog provided,-   (5) Frequency response,-   (6) Maximum volume level,-   (7) Run time per track,-   (8) Length or rate of advertisement insertions,-   (9) Quality of disc jockey (DJ) commentary,-   (10) Quality of content matching to personal profile (would be used    in, for example, a layered multicast scenario), etc. Of course, the    above list is not exhaustive and those skilled in the art would    recognize that other qualities could be attenuated or degraded.

The system 10 is also operative to designate particular zones, such as“dead zones” or “high quality zones”. Thus, in particular areas wherethe place of business does not wish to provide any type of signal at allbecause a competitor's business is located in that zone, the system 10designates this area as a dead zone to ensure that customers of thecompetitor would not receive any of the media content in that area.

On the other hand, a place of business transmitting a signal may havecertain premium areas such as areas adjacent to the signal origin at theplace of business whereby users in such high quality zones are able toobtain access to the signal by paying, for example, a monthly fee toreceive such access. As an example, users in such high-quality zoneswould have access to encryption keys that correspond to higher samplerates or other forms of increased access to a media library such asmusic library 35 as shown in FIG. 1.

The present invention also contemplates that the system 10 is operativeto allow the place of business which is transmitting the signal to grantindividual user-based “upgrades” to the type and quality of proximityaccess that is allowed in any zone. For example, a user 15 who makes apurchase at the place of business from which the signal is originatingmay then have access to a higher sample rate and at a greater distanceaway than another user who has not purchased anything yet from the placeof business. This would serve as a type of customer loyalty program.

Of course, such individual user-based upgrades are not limited to theone described above and could likewise be based on, for example, theduration that a user 30 has been in a particular zone. For example, auser who stays in a particular proximity zone for a particular length oftime may be granted more access or higher sample rates of media contentthan a user who just entered the particular proximity zone.

The present invention also contemplates providing some type ofindication to the user 15 on, for example, their mobile device 50, inorder to apprise the user of any benefits that he will have access to ashe moves closer to the target zone or point of origin of theProximityCast or system 10. For example, the user may be provided with asimple map that currently indicates how the signal is being attenuatedthe further a particular proximity zone is away from the signal originat the place of business. Thus, for example, the user 15 would receiveon his mobile device 50 the particular portion of the full media library35 which is available to him based on his distance away from the signalorigin at the place of business. The indication could be done in anysuitable fashion such as showing more or less bars on the mobile devicescreen or by showing a dial which indicates the percentage of the musiclibrary 35 which is available to the user 15, or the like.

As noted above, in one embodiment, the signal transmitted by the placeof business to users in a proximity zone is a content stream. Thecontent stream is streamed to users depending on the encryption key towhich they have access and which is directly tied to their actualphysical location. As was also noted above, an IPv6 type networkenvironment may be utilized wherein the signals to users in a particularzone is a content stream wherein the content is made available via amulticast stream, allowing multiple users access to the content.Moreover, the multicast may further be layered thus allowing multipleinstances of the content at different quality levels available at thesame multicast address. In such a case, different encryption keys (basedon location) would then be used by various users to gain access to thedifferent quality levels in the layered multicast.

Alternatively, several different multicast streams may be deployed withseparate multicast addresses. A unique key would then be required foreach multicast based on location. In both of the above-describedmulticast scenarios, the encryption keys would quickly age out requiringnew encryption keys to continue the decryption (i.e., each encryptedstream would constantly be changing its encryption key to keep up withthe various users changing locations).

In another embodiment, according to the present invention, theabove-described multicast may be made available via unicast circuits.This type of unicast scenario would be beneficial in less dense listenerenvironments (e.g., environments where there is much less pedestrianand/or automobile traffic, or less living units such as apartments,townhouses, etc.). In this embodiment encryption keys could bedistributed as in the multicast, example, or the unicast could beinitiated based on authenticated location of each user (i.e., notrequiring encryption). However, in that case, the device location wouldneed to be continuously monitored to determine when to change thequality of the content.

In another embodiment consistent with the present invention, the mediacontent already resides in the user's device. In this case, the place ofbusiness transmitting the signal would utilize the signal to unlock thecontent and make it usable based on the location of the user 15.Moreover, in this scenario, the user's device would require moresecurity and, since the content is already resident on the user'sdevice, the encryption format cannot change. In this embodiment, forexample, a rights expression language (REL) file or entry would be usedto control the quality playback of the signal. In order to adjust thequality level, the player may have access to multiple versions of thecontent, or the player may degrade the quality of a high-quality versionto the correct level.

Consistent with the present invention, the system 10 is operative topermit each proximity zone to grant varying levels of access to themedia library 35 of the place of business. In that case, the user 15 maysimply pick the particular media content they wish to listen to.Alternatively, the system 10 may define which portion of the library 30is used to conduct a stream, so that the user cannot pick and choose theindividual songs, for example, that will actually play over their mobiledevice 50.

It is also contemplated that the system 10 may query/receive contentpreferences associated with mobile devices 50 of users 15 in proximityof the place of business and then use that information to determine howto customize various proximity zones. Thus, for example, a particularproximity zone is defined as an aggregate of profiles received, forexample, from mobile devices 50 of users, in or nearby a proximity zone.From this, a proximity zone is then created for access/streams tocountry music because the majority of user devices in that zone preferthat genre of music.

In a further aspect of the customized proximity zone, the system 10 mayestablish a personalized proximity zone for each particular user 15. Forexample, a set of personalized proximity zones are established for user15 that grants that user access to different parts of, for example,media library 35 featuring rock genre. In this regard, the differentproximity zones may employ techniques to incentivize users to comecloser to the place of business. For example, if a particular user 15exhibits a profile indicating a preference for rock music, the system 10may create a series of proximity zones (and indicators) that provideprogressively more access to the specific rock bands as the user comescloser to the place of business's actual physical location.

Furthermore, in situations where profile analysis is either inconclusiveor unavailable, the system 10 is operative to adapt the definition ofeach proximity zone based on the usage of the content, streams, etc. Forexample, the system may start by providing access to a whole range ofmusic genre within a provided music library 35 for each proximity zone,but then later adapt the zone definition to focus on, for example,country genre since that is what a majority of users 15 are currentlylistening to.

It is still further contemplated that the system 10 can adapt the numberof zones and zone definitions (e.g., shape, capabilities, content, etc.)of each zone based on the density of devices in the zone and time ofday. For example, at five o′clock in the morning, very few users havingmobile devices are nearby the business entity originating the signal. Asa result, the system 10 establishes one proximity zone that provideshigh quality access to all of its content streams. Later on in the day,for example, at 8 am when a larger number of users having mobile devicesare present in the area, the system 10 may split the working area intoseveral proximity zones with progressively better quality access, etc.,in a direction leading closer to the place of business originating thesignal.

The present invention further contemplates that the system 10 can trackand project the movement of the user's mobile device 50 to determine howto define and adapt proximity zones. For example, a user 15 having amobile device 50 is projected to walk tangentially through a workingarea in which the proximity zones can be constructed. The system 10 isoperative to adapt the proximity zones for that particular user 15 suchthat the proximity zones are shaped with respect to the mobile device'spath. In addition, the system 10 keeps track of the user's mobile device50 information so that it can distinguish between new mobile devices andmobile devices which the system has previously identified. This allowsthe system 10 to construct more enticing proximity zones for new users.

EXAMPLE A Proximity Encrypted ProximityCast (e.g., System 10) of a MusicLibrary from a Commercial Cafe Location

With reference to FIG. 4, a commercial cafe C located on the corner ofRiverside and West 281 h Street in Richmond, Va., wants to provide itscustomers with “proximity based access” to a comprehensive,easy-listening and properly licensed music library 35 (see FIG. 1). Thecommercial cafe C is represented by the circular object in FIG. 4. Thecommercial cafe C will use the proximity based access as an inducementto those customers equipped with a suitable music related music devicesuch as mobile device 50 to enter their location and purchase coffee,food, etc. While FIG. 4 illustrates the proximity zones havingever-increasing concentric circles as you move away from the commercialcafe C, the present invention is not limited to such a configuration.For example, the proximity zones may have any type of geometric shape,and can be a set of non-contiguous geometric shapes for a proximityzone. Moreover, a proximity zone can also be three-dimensional, e.g.,the first story of a building next-door to the commercial cafe Ccontains shops and is included in a proximity zone, but the floors aboveit have offices and are not included in the proximity zone.

The commercial cafe C also wants to provide some portion (e.g.,attenuated portion) of the music library 35 to potential customers thatare in the surrounding area. For example, such an attenuated portion ofthe music library 35 could be provided to those visitors to the sectionof Riverside Park P shown just to the north of the commercial cafelocation C and who may be possibly induced to visit the commercial cafelocation C.

The commercial cafe location C would further like to control the typeand degree of the attenuation of the media content available based onthe user's relative proximity to the location. In that way, nearby userswould get some value from being near the location,—but would get agreater value by actually going to the location of the commercial cafeC.

The system 10 allows the commercial cafe C to control the intentionalattenuation/degradation/availability of their signal in the surroundingarea depending on distance (and direction) from the signal origin. Theattenuation can take the form of decreasing sample rates for the tracksin the library, decreasing the size of the available library, decreasingdurations for the musical tracks provided, etc., or any combination ofthese factors (see also the non-limiting list of qualities set forthabove).

As shown in FIG. 4, the commercial cafe location C is managing thesample rate of the music that will be provided to users in proximityzones surrounding the location. As noted above, the commercial cafelocation C is represented by the circular object in the center. For anyindividual proximity zone, the location has extremely fine-grainedcontrol over other qualities like track duration, maximum volume, rateof ad insertions, quality of profile matching, etc.

With the settings for sample rates, as users in the surrounding areamove further from the location, the system can verify their location andthen provide those users with particular encryption keys that areassociated with the appropriate proximity zone.

As is also shown in FIG. 4, the location of the commercial cafe C hasadditionally utilized the proximity zone interface to create a dead zonefor their signal. Thus, no encryption key will be provided for thisarea, such that the music library will be unavailable in that sector.The circular object on Hillcrest Road represents a competitor cafelocation R for which the commercial cafe location C does not want toprovide any access or service to their music library 35.

FIG. 5 is a flow chart that illustrates the operation of the method andsystem for providing proximity-based quality for multimedia contentaccording to an exemplary embodiment of the present invention. To begin,a user 15 travels within proximity of a place of business, for example,from the commercial cafe C as discussed above (step S100). The system 10determines whether this particular user 15 should receive alicense/encryption key (step S200). If the system 10 determines thatthis user 15 should not receive an encryption key, the system thendetermines whether the proximity zone is a predetermined dead zone, suchas, where a competitor's location R exists (step S300). If the user isin a predetermined dead zone, then the system intentionally blocks themultimedia content (step S400). This would occur in the dead zoneoccupied by a competitor's location R wherein the commercial cafe Cwishes to avoid transmitting their multimedia content to thecompetitor's location R. If the user is determined not to be within thedead zone, the system will again determine whether the user 15 shouldreceive the key and possibly block the key if there is some other reasonfor not granting access.

While step S400 refers to intentionally blocking the multimedia content,the present invention is not limited to this configuration.Alternatively, the system 10 could be operative to prevent the mobiledevice 50 from using the content stream. For example, the system 10 mayoperate to change encryption keys on a periodic interval, and the mobiledevice 50 in the dead zone would not be provided with the updatedkey(s).

If the user is determined to be in a proper proximity zone and thusshould receive an encryption key, the system 10 next determines whatquality level of multimedia content the user 15 should receive (stepS500). If the user 15 is moving closer to the commercial cafe location(step S800), then the system 10 is operative to, for example, increasethe user's access to the full music library, improve the quality of thepresentation of the multimedia content, etc. (step S900). Once the user15 has actually entered the commercial location, full access to themultimedia content is granted to the user 15 (step S1000).

On the other hand, if the user is determined by the system to be movingfurther from the commercial location (step S600), then the system 10 isoperative to, for example, decrease the user's quality level of themultimedia content by intentionally attenuating the presentationquality, etc. (step S700).

In the example shown in connection with FIG. 4, the commercial cafélocation C not only decreases the sampling rate as user's 15 movefurther away from the store itself, but also decreases the portion ofthe full music library 35 that an individual user 15 can see (also basedon the user's physical proximity to the store). In this regard, users 15may be provided with a simple, graphic means on their mobile devices 50,for example, smart phones, to understand what “quality” of themultimedia content they will receive, depending on their proximity tothe store. As discussed above, such graphical means can be in the formof a map similar to what is shown in FIG. 4, a number of bars, a dialshowing from zero to 100 percent of the available library, or any othersuitable indication devices to show the user the quality of themultimedia content they will receive, or the amount of access to themusic library 35 to which the user will be granted access.

As was noted above, an aspect of the present invention is to incentivizeend users 15 to come closer to the center of the proximity zones, i.e.,the area where the greatest value is available, such as in the cafe. Inthis regard, the system 10 may provide end users 15 an indication(visible or audible or both) that moving into another zone will providesome benefit, and that moving to the center zone will provide thegreatest benefit.

For example, in the “proximity-zone enabled” commercial cafe locationnext to the park as shown in FIG. 5, an end user 15 might see a visibleindicator or alert on their handheld mobile device 50 of what benefitsthe proximity zones around him will provide. There are many ways torepresent this to the user 15 and one of these is illustrated in FIGS. 6and 7. An alternative embodiment of this could be an audible indicatorthat the user is getting “warmer” or “cooler” in respect to the valuesprovided in the related zones. Perhaps the user 15 would receive anaudible introduction by the system when they enter each zone and anaudible indicator that they are moving closer to the center zone—alongwith an indication of what benefit that will provide.

An exemplary use case for a visible indication of the zones:

-   1. As shown in FIGS. 6 and 7, a user 15′ is looking at a map display    of the area he is currently in using his networked handheld device    50′—the user 15′ is represented by the small circle at the upper    left.-   2. The system 10 has overlaid a set of visible proximity zones    surrounding the cafe's C location on the map, and each of these    zones represent the kind and size of the media library this user    will have access to in each zone.-   3. The system 10 has created a custom set of proximity zones for    this user based on the user's 15′ profile—this user is interested in    Jazz and so the system has tailored the zones to especially appeal    to this user 15′.-   4. As the user 15′ clicks on each of the zones, the system 10    indicates what kind of signal is available in that area.-   5. When the user 15′ clicks on the zone immediately surrounding the    cafe C, he sees that in that zone he will have access to the “full    Jazz library” (see FIG. 6).-   6. When the user 15′ clicks on the yellow proximity zone (the zone    furthest away from the center of the zones and the zone he is    currently in) the user 15′ sees that he will have access only to a    part of the library—Bebop (a subset of the Jazz Library) (see FIG.    7).-   7. Similarly, the other zones indicate which portions of the library    are available to him in those zones when the user 15′ clicks on    them.
